我正在尝试将在W3Schools上找到的这个函数的经度和纬度设置为一个变量（我们只是说yand z），然后我需要显示y：

<script>
var x = document.getElementById("demo");
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}
function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude; 
}
</script>

例如，如果我的经度 ( y) 是 10，纬度 ( z) 是 15，那么它会显示

y=10
z=15

你的意思是这样吗？

<!DOCTYPE html>
<html>
<body>

<p>Coords will load momentarily.</p>



<p id="demo"></p>

<script>
var x = document.getElementById("demo");

var lat = '';
var lon = '';

function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else { 
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position) {
    lat = position.coords.latitude;
    lon = position.coords.longitude;
    x.innerHTML = lat + " " + lon;


}

getLocation();
</script>

</body>
</html>

您不必像我一样在全局级别声明值，但认为它可能很有用，因此您可以在函数之外访问它。
